by yssie » May 5, 2010 I have heard both: 1. Plat./silver are softer and more easily scratched than gold, so gold rings/pendants will eat plat./silver rings/chains (though plat. can presumably be repolished with negligible metal loss). 2. Plat./silver are soft, so they pick up grit and become abrasive, and will eat away at adjacent gold which does exhibit this property. What actually happens?
